Final answer:
In the described scenario about employment, the concept of statistical discrimination in Mathematics is demonstrated. For the survey of high school seniors, the 50 percent figure planning to attend college is classified as a 'Statistic'.
Step-by-step explanation:
The concept under discussion relates to statistical discrimination which falls under the umbrella of Mathematics, more specifically Statistics. This concept is typically explored in a College level course, where students delve into the applications of statistics and probability in various fields such as economics and human resources.
In the scenario described, an employer uses previous experience, education, and potentially biased statistical assumptions to make decisions about hiring. This is where the theory of statistical discrimination comes into play because it involves making decisions based on partial information combined with statistical data.
The survey of high school seniors and their plans for education and employment would result in a statistic. Therefore, the answer to the question about what the 50 percent represents is B. Statistic. This refers to any summary measure that is calculated from a sample of data, which in this case is the 50 percent of high school seniors planning to attend a four-year college or university.
